If I may offer my opinion,
The costs of inputs for framelocks would travel down to the consumer and I think Ernie wants to moderate the speed at which his company grows. The fact that he offers the CQC-12 and the HD-7 is good, but many people find the price prohibitive--even at grey market prices. If he were to make framelock versions of the rest of his knives, one could be certain that prices would jump up for almost all models to offset costs of designing a new slab, milling them, as well as the huge increase of titanium consumption. A 179.00 dollar CQC-B will suddenly hit the 200 dollar mark given a year and a fair number of knife consumers will just throw their hands up and regard Emerson with the same air that many people regard Strider with--"What's the big idea?"
It's really too bad at the costs of the HD-7s. I've gotten all of my Emersons from the grey market and I agree with you almost entirely, STR. If would be nice if Emerson offered more framelocks, but I argue issues of cost, and practicality. Also, I'd like his company to focus more on QC issues than coming up with new knives. Personally, I think the CQC-15 is silly looking and offers nothing new. It doesn't bother me that the screws have to be adhered with loc-tite, but it does bother me that the current pivot screws seem to fade very easily compared to his older models. The clips are also, for a lack of a better word, crappier than before. I just can't help quite shake the feeling that overal quality has really been compromised somewhere.
Emerson is a luxury brand knife, and most average people would probably run the argument that carrying anything beyond a Swiss Army knife in the pocket is going overboard, save policemen, service personnel, etc. in terms of going for a blade that will perform for a very reasonable price, I opine that Cold Steel is very hard to beat. On the other side of the spectrum you have Strider Knives. I have no opinion of Mick Strider so I'm not going to say anything about him but I really do think that his 400 plus price for his knives have their place. Every consumable has its luxury and economical sides, and Strider is very definitely more flash than utility. I think people will buy Strider not because Strider is necessarily a superior cutting, prying, stabbing tool, but because he or she wants to buy the Vacheron Constantin of knives.
So I admit it, Emerson has liners that don't really fill me with confidence. I've had trouble with both of my EDC Emersons. But I really don't think that this will be changed soon because of the inherent grace of the slab, liner, backspacer, liner, slab formula. It's simple, people are willing to pay for it, and most people will not likely encounter a situation where their liner locks will fail because most people would have opportunity to run. Most of us guys like to carry knives because, let's admit it, it's a legal way to boast a certain level of masculinity.
In the meantime, I'll hard-use my HD-7 for a few more years until even it gives out.
